An Integrated Digital Image Correlation (IDIC) method has been applied to the cold rolling process, images clearly visualise geometry of roll bite and inlet zone. A key, novel finding is that despite using coils applying entry tension, strip can enter asymmetrically in mill. Moreover, it shown asymmetric feeding results an uneven lubricant film thickness between top bottom surface. detailed fee...

High-resolution grating x-ray diffraction from a periodic quantum-wire structure is shown to be highly sensitive to strain-field variations near a surface or an interface. Information on two types of strain gradients can be obtained: a longitudinal gradient, which can produce asymmetric diffraction profiles, and a transverse gradient, which can generate additional diffuse intensity streaks in r...

Abstract. Dynamic recrystallization of high-speed steel (HSS) M2 occurs through a discontinuous mechanism, involving nucleation and growth strain-free grains. The initiation completion dynamic (dDRX) must be carried out in single rolling pass. time for 99% dDRX depends on the critical strain, strain rate equivalent that generated workpiece material level plays key role terms possibility to comp...

To process ingots of Fe–Ga alloy single crystals into wafers, Fe–17% Ga were cut using multi-wire sawing or electric discharging and rolling. Further, their properties magnetization magnetostriction analyzed electron backscatter diffraction (EBSD) X-ray (XRD). It was observed that the curves changed with increasing rolling reduction. Although negligibly affected by deformation, shape curve as-g...

For some Si-killed steel grades, it is desirable to obtain calcium or manganese silico-aluminate inclusions with low-melting temperatures, which form a glassy phase at low temperatures and are easily elongated reduced in size during hot rolling. However, these sometimes exhibit coarse crystallization changes heat treatment before rolling, affects the rheological properties of inclusions. In pre...

Asymmetric Fano resonances are predicted to occur in the linear electronic conductance across a shallow quantum well in a high magnetic field. The Fano lineshape results from the interference between direct transmission and transmission via a quasi-bound state in the well which is weakly mixed with the continuum by tilting the field. The resonance width increases with tilt angle but general S-m...

• Inter-layer, stacked-layers and post-build rolling is modelled to investigate their interaction with wire arc additive manufacturing (WAAM) for mitigating WAAM residual stress distortion. Difference in mitigation efficacy of using flat roller slotted demonstrated explained. Influence depth cyclic deposition alter plastic strain that causes determined analysed different process conditions. Hyb...
